BERRIES & ASPARAGUS REDUX
Berry Enticing
Berries are making it harder to get things done around here. Not because they are so much trouble to grow, but because I’ve planted them here, there, and everywhere. Wherever I walk I seem to come upon a berry bush. Who can resist stopping to graze? This year is a particular bountiful year for berries.
I can’t even walk to my mailbox without being confronted. First, there are lowbush blueberries hanging ripe for the picking over the stone wall bordering the path from the front door. 
The wall supports the bed of them planted along with lingonberries, mountain laurels, and rhododendrons. These plants are grouped together because they are in the Heath Family, Ericaceae, all of which demand similar and rather unique soil conditions. That is, high acidity (pH 4 to 5.5), consistent moisture, good aeration, low fertility, and an abundance of soil organic matter. The small blueberries send me back to many summers ago in Maine when a very young me hiked in the White Mountains and picked these berries from plants growing amongst sun-drenched boulders. Care needed: mulching in autumn, and cutting a portion of the planting to the ground with a hedge trimmer every second or third winter.
A few feet further the path ends and I come to the driveway, and here’s a 50 foot long hedge of Nanking cherries (berry size, but a drupe fruit, not a berry), whose season is almost over. For the past few weeks the stems were so solidly clothed in cherries that you could hardly see the branches. The cherries have a very refreshing flavor on the spectrum between that of sweet and tart cherries. Care needed: winter pruning — very nonexacting — to keep the bushes from growing too large.
Perhaps later, once back in the house, I’ve got to walk out the back door to the compost pile. Hmmm. Gooseberry plants are enticing me with their stems that are arching to the ground under their weight of berries. Can’t pick a little from just one plant. I’ve got to eat a few of each of the over dozen varieties. My favorites? Hinnonmaki Yellow, Poorman, Black Satin, Red Jacket, and Captivator.

It’s a funny thing about gooseberries. If I pick a bowl of the berries and then bring them indoors to eat, they don’t taste as good as the one’s eaten bushside. It’s not just me; Edward Bunyard, in his 1929 book The Anatomy Of Dessert, wrote that the “Gooseberry is of course the fruit par excellence for ambulant consumption.”
Care needed: winter pruning to get rid of the very oldest stems and make way for younger ones; and to reduce the number of newest stems if they are overly abundant.
Okay, I finally made it to the compost pile. Now to check what’s going on in the greenhouse. Uh oh, I have to walk past black currants, one of my favorite fruits and now at their peak flavor. Their flavor is intense, intensely delicious to me. I grow mostly the variety Belaruskaja, which has just the right amount of sweetness to balance its almost resin-y flavor. Care needed: annual winter lopping to the ground of all two-year-old and some one-year-old stems.
And right next to the black currants are black raspberries, also now at their peak flavor. The heavy crop of berries are arching some of the longest stems within reach of our ducks. I can share a few berries with them. Black raspberries grow wild all over the place in much of this part of the country. Wild ones are good. I prefer the named variety, Niwot, that I planted because it is one of two varieties that can bear two crops each season. For fruit size, flavor, and abundance, it’s worth growing even for just its summer crop. Care needed: summer pinching of tips of new stems to induce branching; winter pruning to cut away all two-year-old stems and thin out one-year-old stems, and to shorten branches to 18 inches; and tying stems to posts to hold them up.
Finally, I make it to the greenhouse. Leaving it, I’m confronted with two mulberry trees, the variety Illinois Everbearing and the variety Oscar (what a funny name for a fruit tree). No danger of the mulberries delaying my progress because I know that the birds are taking all of them. Illinois Everbearing, true to its name, will continue to bear into August. Perhaps by then the birds will tire of them or move on to other fruits, leaving some for me.
One more enticement, one of the best, before going back indoors — Fallgold raspberry. 
This variety, carrying genes of some species of Asian raspberry, has a sweet, delicate flavor unlike any other variety. Physically, the berries are similarly sweet and delicate, a pale, pinkish yellow. Their fragility makes them a poor commercial fruit so you won’t see them for sale. Grow them.
Asparagus Cutting?
Seems like last week’s blog post about my method for reducing weeds in the asparagus patch caused a lot of confusion. I wrote that I cut down all the spears before applying compost and wood chips, and many people thought that was not supposed to be done until autumn.
During the harvest season, which here is from the time the spears first show until the end of June, the spears are constantly being cut down for eating. All are regularly cut, even those too spindly for eating. Doing so helps starve out asparagus beetles, which are gone by July.
So consider my final, early July lopping back of any and all spears just like a final harvest. From then on, spears are left grow to their heart’s content, fueling the roots for next year’s spring and early summer harvest. The bed gets its final cutting down in autumn, when the ferns yellow to indicate that they’re no longer feeding the roots.
I was a little nervous about the compost plus wood chip smothering asparagus plants in addition to weeds. Not to worry. It’s a few days after the treatment and some fronds are already a few feet high. And so far, no weeds.
More details about growing and use of berry (and other) fruit plants can be found in my books Grow Fruit Naturally and Landscaping with Fruit.
“SPARROWGRASS” RENOVATION
The Season Ends
Asparagus season has ended here now, after more than two months of harvest. From now till they yellow in autumn, the green fronds will gather sunlight which, along with nutrients and water, will pack away energy into the roots, energy that will fuel next year’s harvest.
In addition to dealing with the weather, the plants have to contend with weeds. I have to admit, despite being the author of the book Weedless Gardening, that my asparagus bed each year is overrun with weeds, mostly two species(!) of oxalis, creeping Charlie, and various grasses. Also weeds parading as asparagus, self-sown plants. This, even though I planted all male varieties. Any batch of male plants typically has a certain, low percentage of female plants. (Still, my garden is weed-less even if it’s not weedless.)
I always wondered about the recommendation to plant asparagus crowns in deep trenches that are gradually filled in with soil as the new plants grow. I read that one reason is that crowns deep in the soil results in thicker, albeit fewer and later, spears. But as if to decide for themselves, research also shows that , over time, shallowly planted crowns naturally settle deeper into the ground, and deeply planted crowns inch upwards.
Another reason for deep planting is, perhaps, to protect the crown from tiller blades or hoes. I don’t till and, since the plants anyway take the matters in their own hands, I set my asparagus, years ago when I planted them, just deep enough to get the crowns under the ground.
Weed Control(?) for Next Year
But back to the weeds in my asparagus bed . . . This year I’m determined to get more of the upper hand with weeds. To whit: Yesterday I cut everything — weeds and asparagus — in the bed as low as possible. A bush scythe, which is a scythe with a short, heavy duty blade, does this job easily and quickly; a weed whacker might also work. One year a battery powered hedge trimmer got the job done. For me, the scythe works best.
In years past, I would cut everything to the ground, as I did this year, and then I’d top the bed with a couple of inches of wood chips.
This year, to get better weed-less-ness and to offer the asparagus plants a treat as thanks for the many spears that went into cold soup, hot vegetable dishes, and the freezer, I offered them compost. Although I make lots of compost, that compost is generally reserved for beds within the vegetable garden proper and potting mixes as well as, this year, my newly planted grape vines, and pear and apple trees.
Asparagus is worth it, so I dug into my most finished compost bin, filled up two garden carts, and slathered a one-inch layer of compost over the whole bed. That inch of dense, dark compost should go a long way to smothering small weeds, which have little reserve energy. The compost then got topped with a couple of inches of wood chips. 
The compost will nourish the asparagus . . . and the weeds, most of which I hope will be sufficiently young or weakened to not push up through the compost and the wood chips to light.
Compost Needed
That was a lot of compost to part with. No problem, because I’ve also been making lots of compost. Plus, a few bins I built last year, each with about one-and-half cubic yards of compost, are ready to use or will be so in the coming weeks.
The bins themselves are made from 1×6 boards of composite wood (a mixture of waste wood, recycled and new plastic, and some type of binding agent), such as used for decking, notched to stack together Lincoln-log style. It keeps moisture and heat in, and scavengers and weeds more or less out, and doesn’t degrade, as did my previous wood bins.
I feed my compost pets — earthworms, fungi, bacteria, and other organisms — hay from my small field, manure from a nearby horse farm, kitchen waste, old garden plants, and anything else biodegradable. The latter category has included old leather shoes and garden gloves, jeans, and, as an experiment, biodegradable(?) plastic spoons.
The compost also gets occasional sprinklings of soil, to add bulk, and ground limestone. Periodic liming is generally needed to counteract the acidity of most soils of northeastern U.S.; my soil gets limed indirectly, via the compost.
Water is commonly the most limiting ingredient in home composts. Lots of water is necessary to percolate down into a pile. Rather than getting bored with a hose wand, after finishing an extended composting session, I set up a small sprinkler on the pile, whose spread is as wide as the pile, to gently water for about 20 minutes.
Of course, the devil is in the details: how much of each ingredient to add. Not to worry, though. Any pile of organic materials will eventually turn to compost.
For my piles, I check moisture with a REOTEMP long stem moisture meter and monitor progress with a long stem compost thermometer. This time of year temperatures of the piles soar to 150°F within a few days.
My asparagus bed is worth all this.
GOOD BERRIES, BAD(?) BERRIES
Sad, Then Happy
A sad day here on the farmden: the end of blueberry season. Frozen blueberries, that is. Seventy quarts went into the freezer last summer, and a lot more than that into bellies, and now they’re all finished.
A happy day here on the farmden: the first of this season’s blueberries are ripening. These blueberries, and those that were in the freezer, are the large “highbush” (Vaccinium corymbosum) varieties commonly found fresh on market shelves. Also ripening now are “lowbush” (V. angustifolium) blueberries, growing as a decorative, edible ground cover on the east-facing slope near my home.
I’ve said it before but I’ll say it again. After many, many years of growing fruits in my not-particularly-good-for-fruit-growing site, blueberries — a native fruit — have always yielded well. Two most important things are adapting the soil to blueberries’ unique requirements, and keeping birds at bay. Birds at bay? Best is a walk-in, netted area.
Soil for blueberries needs to be very acidic, with a pH between 4 and 5.5, made so, if needed, with the addition of sulfur, a naturally mined mineral. The pelletized form is best because it’s not dusty. Blueberry roots need good drainage and consistent moisture. They thrive in ground rich in organic matter, maintained with an annual three-inch topping of some weed-free, organic material such as wood shavings, wood chips, straw, pine needles, and autumn leaves.
(That’s the bare bones for success with blueberries. For a deeper dive into growing this healthful, delicious, reliable fruit, stay tuned for my soon-to-be-aired blueberry webinar.)
And More Berry-Like Fruits Coming Along
Just as last year’s apples were losing their crispness and tang and I needed a change from oranges, other berries, in addition to blueberries have started changing color, softening, and turning flavorful.
Black currants are another one of my favorites now ripening. They admittedly have an intense flavor not to everyone’s liking. But everyone likes black currants conjured up into juices, pastries, or jam. Variety matters. My favorites are Belaruskaja, Minaj Smyrev, and Titania.
Don’t think black currants taste anything like “dried” or “Zante” currants. Those are raisins, originally made from “Black Corinth” grapes, a name then bastardized to “black currant.”
Like blueberries, black currants are easy to grow. But they have no special soil requirements, they fruit well even in some shade, and deer rarely eat the bushes, and birds rarely eat the berries.
Another tasty morsel now ripe is gumi (Elaeagnus multiflora). Birds usually strip this shrub clean of fruit, except this year the crop is so abundant that neither I nor the birds can make much of a dent in it. The berries are a little astringent if not dead ripe. And not at all if the fruit is processed; last year I cooked them slightly, strained out the seeds (which are edible), and blended it before drying it into a “leather.”
The gumi shrub itself has silver leaves, providing an attractive backdrop for the red fruits. The flowers are extremely fragrant, and the roots enrich the soil by taking nitrogen from the air (with the help of an actinomycete microorganism.)
Also now abundant, with plenty for all, is Nanking cherry (Prunus tomentosa), a favorite of mine for beauty and easy-to-grow cherries. The cherries are small, usually no larger than about 3/8 inch. But the single pit is also small. Flavor lies somewhere on the spectrum between sweet and sour cherries, very refreshing especially when chilled.

Another Chance, and Then Another
All is not rosy in the berry-size fruit world. Over the years, I had heard about and tried a new fruit in town, edible honeysuckles. In the past, the plants I tried either died over winter or bore very few, very mediocre berries. Since then, edible honeysuckles have come up in the world, with serious breeding work, and I was given the opportunity to try them again. (As Maria Schinz said, “Gardening is an exercise in optimism.”)
But first, what is an edible honeysuckle, which now goes under better names. If called “honeyberry,” it usually refers to Russian species such as Lonicera caerulea app. kamtshatica or edulis. Haskap is a Japanese name applied the Japanese species L. caerulea spp. emphylocalyx, or to hybrids of this species with Russian species. Pure Japanese species varieties are sometimes called Yezberry, after the Island of Hokkaido, called Yez or Yezo Island where they are found. The Japanese species and hybrids are less susceptible to spring frosts than the honeyberries.
This spring I planted out two Yezberry varieties, Solo and Sugar Mountain Blue. The small, blue berries ripen early, and I was eager to give this fruit another try. Solo is bearing. The taste? Awful! Sour, with no other flavor.

But I’m not abandoning edible honeysuckles. I’ve learned that the berries need to hang on the branches for a long time before developing full flavor and sweetness. A number of varieties are available, some of which are, according to others, “Delicious when eaten fresh from the plant” and “a bit like a cross between a raspberry and a blueberry. . . sweetness of a raspberry with a hint of pleasant tartness.” Really?!
Many blue berries are still hanging on my Solo bush. I’ll leave them to hang longer there and perhaps morph from “awful” to “delicious,” and will report back. I have hope for this new fruit, not yet high hopes.
At the very least, honeyberries or haskaps might be able to tide me over from the end of frozen blueberries to the first of fresh blueberries.
